3 Claims. (01. 61- 80),

My invention relates to steel piles and thelike built up of a plurality of parallel juxtaposed members. It may also be used as a .beam or strut.

' The objects of the invention are to provide an inexpensive steel pile that can be made either of new material of standard shape as hereinafter I described or of scrap material, such as used railway rails and the like, and that may, if desired,

be used without pointing; 'to provide a pile in which the metal is so distributed as to form'a central core of sufiicient density to absorb the hammer blows and transmit them to the penetrating end and to resist bending stresses and the tendency to spring under the hammer blows; and to provide a longitudinal passage through the length of the pile to permit e use of a jet to assist penetration if desired. other objects and advantages of the invention will be apparent from the following description, which should be read with the understanding that the several parts of the structure may be varied, as to form, arrangement, or otherwise, within the limits'of the appended claims, without departing from the spirit of the invention.

Reference will be made to the accompanying drawing, wherein Fig. 1 is an end view of one form of mysteel pile.

Fig. 2 is a side elevation thereof, reduced in size.

Figs. 3 and 4 are end views showing two other arrangements of the constituent members.

Fig. 5 is an end view, on a smaller scale, showing a simple arrangement 'of two railway rails which is useful as a beam or strut as well as a pile.

I have herein shown and described my pile as made of scrap railway rails, inasmuch as they provide a cheap source of suitable material. It should be understood, however, that members of other generally similar shape, either new or scrap, may be used, such as I-beams, T-beams, channels, and so forth. It is also to be understood that the number of constituent members used to make each pile is immaterial, from two up, depending upon the size and shape of the members and the size, general shape, and strength desired in the pile.

The pile consists of a plurality of paralle members, such as railway rails 5, arranged preferably, although not necessarily, in symmetrical fashion about a common longitudinal axis, and permanently joined together in some suitable manner such as-welding, as shown at 6. In Figs. 1 and 2 I have shown, by way of example, a simple form of pile composed of three rails 5 synnnetrically arranged with their bases 1 contiguous, the welds 6 joining said bases rigidly together. Obviously, the welds may either be continuous throughout the length of the pile, or made at 5 sufliciently close intervals to provide the necessary rigidity between the several members.

In Fig. 3 I have shown an arrangement in which the rails are positioned with their heads 8 contiguous, the welds 6 joining said heads, and the bases 1 being at the outside of the pile. In Fig. 4 analternating arrangement is shown, the base I of one rail being welded to the head 8 of the next. In Fig. 5 is shown an arrangement of two railway rails placed with their heads 8 together '15 and welded at 6. This arrangement may be used under certain conditions as a pile,'and is also useful as a beam or strut.

It will be seen, particularly in Fig. 3, that there is a concentration of material in the central region of the pile, the rail heads 8 forming a central core well adapted to receive the hammer blows and transmit them to the penetrating end. Moreover, the webs 9 and bases 1 of the rails form angularly related fins and flanges which give the pile great lateral strength to resistbending and to minimize springing under the impact of the hammer. The same general distribution of material is present in the forms shown in Figs. 1, 4'

and 5. 30

It will also be seen from the end views, Figs. 1, 3 and 4, that the aggregate cross sectional area of the pile is comparatively small in relation to its total width; in other words, its ends present no large flat surfaces, and therefore the bottom .or penetrating end need not be pointed, but can It will be obvious that the constituent rails 5 may be of any length, and may be pieced, end to end, by suitable welded or other joints, to make 50 the pile of whatever length is desired. Such .joints should preferably be staggered.

Thus my invention permits the use of old railway rails, or other scrap metal of generally similar shape, in constructing metal piles and the like of any length, strength, and size, at a minimum expense, the only labor necessary being the handling and welding of the rails and such cutting ofi as may be required.

I claim:

1. A metal pile and the like comprising a plurality of parallel members, each member having a flange and a web, the flanges of the members being contiguous and joined together along their meeting edges to form a central hollow core, and said webs extending outwardly therefrom to form stiffening fins.- e

2. A metal pile and the like comprising three or more parallel railway rails, arranged about a common longitudinal axis, each rail having a base flange, a head flange, and a web'connecting said flanges, the flanges of the several rails near-V est said axis being contiguous and permanently joined together along their meeting edges to form a central hollow core, and said webs extending outwardly from said core.

3 A metal pile and the like comprising a plurality of parallel railway rails, each having a base flange, a head flange, and a web connecting said flanges, one flange of each rail being positioned in the central region of the pile, and said central flanges being contiguous and permanently joined together along their meeting edges.-
